EDGE drilling standard pneumatic test equipment is available to suit NQ, HQ and PQ sized cored holes, and can be configured to single or straddle configurations to test large or more specific zones.

Single Pneumatic Test Equipment

Single Pneumatic Test Equipment is designed for testing cored holes whilst drilling progresses to greater depths. The pneumatic system is suitable for testing cored holes to a total depth of 700m. Below this depth, Hydraulic Permeability Test Equipment must be used.

When a zone of interest is identified in the retrieved core sample, the drill rods are moved back a suitable distance, such that the deployed packer equipment can be inflated above the zone of interest. Once inflated (using the Nitrogen gas supply), testing of water injection flow rates at various injection pressures can commence. Injection pressure can be controlled via a bypass system on the injection flowmeter board – supplied as part of the standard equipment.

Straddle Wireline Packer 

Straddle Pneumatic Test Equipment

Straddle Pneumatic Test Equipment is designed for testing specific zones of cored holes once drilling to total depth is complete. The pneumatic system is suitable for testing cored holes to a total depth of 700m. Below this depth, Hydraulic Permeability Test Equipment must be used.

When a zone of interest is identified in the retrieved core sample, the drill rods are moved back a suitable distance such that the deployed packer equipment can be inflated with the two packers straddling the zone of interest. Once inflated, testing of water injection flow rates at various injection pressures can commence. Injection pressure can be controlled via a bypass system on the injection flowmeter board – supplied as part of the standard equipment.
